From 0f58dbae4ab2397dc310e19d171a4bc60fc6c9a7 Mon Sep 17 00:00:00 2001 From: Bill Schmidt Date: Fri, 8 Feb 2013 18:19:17 +0000 Subject: Refine fix to bug 15041. Thanks to help from Nadav and Hal, I have a more reasonable (and even correct!) approach. This specifically penalizes the insertelement and extractelement operations for the performance hit that will occur on PowerPC processors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174725 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Analysis/CostModel/PowerPC/insert_extract.ll | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 test/Analysis/CostModel/PowerPC/insert_extract.ll (limited to 'test/Analysis/CostModel') diff --git a/test/Analysis/CostModel/PowerPC/insert_extract.ll b/test/Analysis/CostModel/PowerPC/insert_extract.ll new file mode 100644 index 0000000000..f51963d56f --- /dev/null +++ b/test/Analysis/CostModel/PowerPC/insert_extract.ll @@ -0,0 +1,16 @@ +; RUN: opt < %s -cost-model -analyze -mtriple=powerpc64-unknown-linux-gnu -mcpu=pwr7 | FileCheck %s +target datalayout = "E-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-f128:128:128-v128:128:128-n32:64" +target triple = "powerpc64-unknown-linux-gnu" + +define i32 @insert(i32 %arg) { + ; CHECK: cost of 13 {{.*}} insertelement + %x = insertelement <4 x i32> undef, i32 %arg, i32 0 + ret i32 undef +} + +define i32 @extract(<4 x i32> %arg) { + ; CHECK: cost of 13 {{.*}} extractelement + %x = extractelement <4 x i32> %arg, i32 0 + ret i32 %x +} + -- cgit v1.2.3
